Claims

[Scope of utility model registration request]

The sliding nozzle device has a surface pressure setting structure along the sliding direction, and a bubbling plate insertion device is provided on the opposite side of the advance/retreat drive device of the metal frame that accommodates the sliding plate having molten metal flow holes, and A moving rail is installed inside the riding nozzle surface pressure setting structure to a position that sandwiches the molten metal flow hole in the sliding direction, and the surface pressure that rises and falls on the moving rail with a difference in level from the sliding surface near the molten metal flow hole is installed. A bubbling plate installation structure in a sliding nozzle device, characterized in that a protrusion is provided on the sliding lower surface of a metal frame that slides on the moving rail and houses the bubbling plate.
